Antisemitism on the left is subtler than on the right. But it's getting worse.

The Sunrise Movement knows a lot about climate change. As the self-described “youth movement to stop climate change and create millions of good jobs in the process,” they have spent countless hours appropriately ringing the alarm bell about the now-quickening pace of climate change, arguing that we must act now before it’s too late.

Last week, however, the Sunrise Movement inadvertently alerted us all to another change in the climate: a slow but steady, unmistakable rise of antisemitism among progressive groups.

It started when its Washington, D.C., chapter issued a statement last Wednesday that it would not speak at a rally later that week in support of D.C. statehood because of the participation of three Jewish groups “that are all in alignment with and in support of Zionism and the State of Israel,” and asked the organizers of the rally to remove all three groups from the list of supporters.

When incidents like this happen, many wave it away, explaining that the real threat from antisemitism is from the far right and those who enable it. There is no denying that right-wing groups pose a material threat to Jewish life in America and to our democracy as a whole. Over the past 10 years, ADL has found that 75 percent of extremist-related murders were linked to right-wing ideology, including the 2018 Tree of Life massacre, the deadliest antisemitic attack in U.S. history. Many of the perpetrators of the Jan. 6 insurrection had ties to the Proud Boys and other extremist groups. And this week, the civil trial begins against the white supremacists who led a violent mob in Charlottesville in 2017, chanting “Jews will not replace us” as they marched down the street.

But that is not the only threat.

To use an analogy that Sunrise and its supporters should understand, right-wing antisemitism is the lethal category-5 hurricane threatening to bring immediate catastrophe. Antisemitism on the left, however, is more akin to climate change: Slowly but surely, the temperature is increasing. Often people don’t perceive the shift, or they choose to ignore it even in the face of once-uncommon storms. But the metaphorical temperature is rising, and the conditions threaten to upend life as we know it.
